What is a Phenol Red?
Phenol red, with the chemical formula C₁₉H₁₄O₅S, is a pH indicator used in various biological and chemical applications. It changes color depending on the pH of the solution:
✅ Yellow at pH < 6.8
✅ Orange to red between pH 6.8–8.2
✅ Pink to fuchsia above pH 8.2
It is commonly used in cell culture media to monitor pH changes. A color shift in the medium signals possible contamination or changes in cell metabolism, making phenol red an essential tool in laboratory environments. Additionally, phenol red is used in pH tests for swimming pools, in clinical tests for gastrointestinal activity, and in various titration methods.
